Yeah, the raised Galveston about 20 feet with fill as I recall. It's
worked
pretty good.

Seem to me we should take all of that delta mud that keeps extending the
Mississippi and use it to fill in the parts of N.O. that can never be
saved
and raise it to 20 feet above sea level. That would take care of a lot of
future settling. It would also shorten the Mississippi channel. The
historic and commercial sections of the city could be left in the "bowl"
as
a major tourist attraction and would be mush less volume to protect and
pump
out. A major major project but better than spending the money on some
other
silly government project.

Silt doesn't make good structural fill because the particle size is too
small. Small particles don't well, and result in soil that moves once you
think you have it put in place.

Where is the runway in Asia they built on silt? The one where they designed
it to sink a foot or so in the first X years, then more or less stabilize?
Unfortunately, it is sinking faster than expected, and they will have to do
it all over again some day in the future.
